NAPPER.

Specification of Letters Patent.

Application filed February 26, 1912.

Serial No. 679,950.

To all whom it may concern Be it known that I, AsA C. BAUM, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Nappers, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improved napper, and I declare that the following is a full, clear, concise and exact description thereof, sufiicient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings, in which like reference characters refer to like parts throughout.

The invention relates particularly to a machine applicable for use in knitting mills where the product is in the form of a tube, being knitted on a circular machine, and the invent-ion consists in the various fea tures shown, described and set forthin the drawings, specification and claims.

In the drawings Figure 1 is a full view of the napper; Fig. 2 is a plan view of the napper, taken on the line 22 of Fig. l and showing the mechanisms which raise the nap in position to operate on a tube of a given diameter, while Fig. 3 is a like view, but with those parts in a different positionadapted to operate on a tube of lesser diameter; Fig. 4 is a partial view of the machine as shown in Fig. 2, but on a larger scale; Fig. 5 is a sectional view of a portion of the machine, on the line 5-5 of Fig. 4; Fig. 6 is a view of parts of the machine shown particularly in Fig. 5 and looking at such parts shown in thatfigure in the direction of the arrow; Fig. 7 is a detail View of a part of the machine, parts being broken away.

Referring to the figures in detail, A represents standards which support a frame B which is in the form of a fiat ring. 0 shows standards mounted on the ring and which support the bed D which is in the form of a ring. The shaft E is mounted in the frame, as in one of the standards G, and carries suitable power transmitting members, represented by pulley F and F, and a beveled gear pinion G. A recessed ring 1 is bolted onto the bottom of the bed A beveled gear 2 is carried on the ring 1 by means of an outwardly projecting flange 3 which lies in a corresponding cutout in the ring 1. The gear 2 is in the form of a ring of the cross-section shown in Fig. 5, and on an inwardly extending flange 4 rests and is secured a ring 6 which is designed to be rotated on the bed D. The bed D has secured thereto a beveled gear 8. The ring 6 has radially disposed cutouts, three being shown in this machine, in which are placed blocks 10 which are adapted to be moved toward and from a common center. Mounted in each of these blocks is a shaft 12 which carries a beveled gear 14 adapted to mesh with the beveled gear or rack 8. The stud or shaft 12 is longitudinally grooved and the gear 14 is formed with a corresponding projection fitting into said groove so that notwithstanding the inner and outer movement of the block 10, the gear 14 sliding along the stud or shaft remains in mesh with the gear or rack 8. It will be noted that the ring 6 is out out, as indicated at 15, for the location of the Patented Dec.3,1913.

gear 14. On the inner end of the stud or a shaft 12 is mounted a gear 17 with which meshes, one on each side, worms 18 and 19 which are mounted in block 10 and which project upwardly above the block and carry the heads 20 and 21 which are suitably clothed for the napping work, and which it is seen revolve in opposite directions.

In the operation thus far described beveled gear pinion G causes the ring gear 2 to revolve, being supported on the ring 1 which is fixed tothe stationary bed D. The revolving ring gear 2 carries with it the ring 6. The gear ring or rack 8 being fixed to the stationary bed D, the revolution of the rings 2 and 6 causes the revolution of shaft 12 by the mesh of its gear 14 with the stationary rack 8, and the revolution of the shaft 12 causes the worms 18 and 19 to rotate and correspondingly revolve the heads 20 and 21.

On each block 10 is fixed a pin 24. An adjusting ring 25 rests on the ring 6 it being out out for gear 14, as seen) and having a tangentially disposed out 27 which receives the pin 24. At suitable points in the ring 6 is fixed a stud 28 which projects through slot 29 cut in the adjusting ring 25, and a washer 30 and nut 31 are provided so that the adjusting fixed position relative to the ring 6. By means of these mechanisms the adjusting ring, when loosened. may be moved a given distance in either direction, so that by engagement of the pin 24 in the slot 27 each ring 25 can beheld inchine and the two are formed to inclose feed pipe 36. The feed pipe extends upwardly and has a senncircular turn and extends downwardly over the center of the machine,

as seen in Fig. l. At38 the feed pipe has a vertical cutout which opens into horizontal cutout 39, and the thumb-screw l0 engages the pipe in the slots so that the thumb-screw 40 may be loosened and the pipe may be raised and turned so as to be supported by the engagement of the thumb-nut in the horizontal slot 39. This brings the member 45, to be described, and the portion of the pipe 86 which supports it, above and to one side of the napping members. hen in such position the member a5 is removed. A roll of cloth is supported adjacent the foot of the pipe, as on bar l1 supported in prongs 42 of the bracket 35. The end of the cloth is then passed up through the pipe and brought out at the upper depending end which is at one side of the machine when the pipe is so raised. The end of the tube of cloth is then turned backward on the outside of the pipe and the entire roll of cloth is in that manner fed through the pipe and turned backward on the outside so that it can be fed to the machine, as will be seen.

45 represents a drum of a given size. The size is to be determined according to the size of the tube which is to be napped. The upper end of the drum fits into the upper depending end of the pipe 36 and is provided with a pin e6 which fits into a key hole cutout t? in the end of the pipe 86, so that the drum of whatever size it may be can be fitted into and secured to the pipe 86, and thus the drum will receive the cloth as it is drawn down from the pipe and through the machine. In order to prevent the cloth from being carried around the drum and so twisted by the action of the heads as they travel around the drum, I set into the drum at the top and the bottom small wheels 50 and 51 provided with suitable teeth 52 and supported by their axes resting in blocks 53 suitably secured in proper places in the drum.

Near the bottom of the machine is a roller or take-up, indicated by 55, which is revolved by means of gear or rope 56 carried by a pulley 57 on the shaft E and pulley 58 on the shaft 55.

In operating the machine a roll of cloth is passed inside the tube 36 and turned wrong side out on the outside of the tube. The

tube being in place with member 45 con-- trally located relative to the brushes 20 and 21 the cloth is drawn off the tube onto roller 55 being napped as it passes over member 4C5 by the rotating brushes 20 and 21. By the means described these brushes are caused to revolve and the entire set of brushes rotates around member 4L5. The brushes, as also set forth, may be adjusted to nap cloth of various sizes of tube being set, by means of the adjusting mechanisms, at a greater or less distance from the center of the machine.
